The easiest way to make fishnet fabric is with crochet stitches. A wide variety of mesh stitches allows you to make all kinds of fishnet, from plain to fancy. The simplest of these is an arch mesh consisting of single crochet stitches and arches of chain stitches. Work the stitches back and forth in rows to create a rectangular fishnet fabric to use as a market bag. Work the stitches in the round to make fishnet fingerless gloves or even fishnet stockings.
Work row 1. Chain a multiple of four plus two. Single crochet in the second chain from the hook. Chain five, skip the next three chain and single crochet in the next chain. Repeat across. Turn.
Work row 2. Chain five. Single crochet and chain five in each chain five loop across to last chain five loop. Single crochet in last chain five loop, chain two and double crochet in last single crochet. Turn.
Work row 3. Chain one and single crochet in the first double crochet. Chain five and single crochet in each chain five loop across, ending with a single crochet in the third chain of the turning chain. Turn.
Work subsequent rows. Repeat rows 2 and 3 until the fabric reaches the desired length. Fasten off.
Join with a slip stitch in the first stitch at the end of each row before turning to work in the round.
